Hi, im from philippines, our academe has an EMCO Compact5 CNC with motherboard #: A6U105002 this lathe machine was purchased 10 yrs ago... and the personnel in-charge went out from the academe...and until now it has never been used.... so for this reason the college has decided to make used of the machine... one of the problems we currently encountered was the RS232 cable... we made our own cable which will be attached from the Computer going to the EMCO Compact5 CNC, thru the RS232 port of the CNC...
kindly check if we are doing the right connections of the DB9 connector:
DB 9 --------> EMCO CNC circuit board # 52
pin # 2:------> PIN B
pin # 3:------> PIN A
pin # 5:------> PIN C
pin # 7:------> PIN D
PIN H & J were of the EMCO RS232 port were connected together...
